Specification of Letters Patent.

Patented July 20; 1909.

Application filed December 21, 1908. Serial No. 468,663.

To all whom it mag concern:

Be it known that 1, ROBERT V. LYON, of

State of New York, have invented certain new and useful Im rovements inBottle- Sealing Devices; and do hereby declare the follow ng to bea-full, clear, and exact description of the same, reference being had.to the accompanying drawings, forming a part of this specification, andto the reference-numerals marked thereon.

The resent invention relates to bottle sealing devices of the type inwhich a cap is employed and is secured to the exterior of the bottle forholding "a sealing. material infirm contact with the walls-of the mouthof the bottle; and an object of this invention is to ing tool of thekind cooperating with the cap retaining me s and the upper surface ofthe cap, may be e ctively engaged with the latter to prevent accidentalslipping of the tool and injury to the hands oft e operator.

Tothis and other ends the invention consists in certain improvements andcombina tions of parts all as will be hereinafter. more fully described,the novel features being pointed out inthe claims at the end of thespecification.

In the drawings: Figure 1 is a verticalsec tion of the upper ortion of abottle with the improved sealing evice thereon, a tool being shown insection to illustrate the operation of the invention; andFig'. 2 is aperspective view of the sealin device and the removing tool cooperatingt erewith.

Referring more particularly to the drawings, 1 indicates a portion of abottle which has an exterior annular shoulder 2 about its up er end. A,sealing device or disk 3 prefera ly in the form of yielding materialsuch as cork rests upon the upper ed e at the mouth of the bottle andispreferab y carried within "and covered by a cap that may be made fromsheet material such as sheet metal.

has projecting downwardly from eriphery a retaining device which pref-Ely consists of an annular flange corruits era

gated at its edge, the depressed portions 4 of ,the corrugations beingengaged with the shoulder 2 on the bottle and the elevated portions 5being adapted for engagement by a removing tool. 1

The removing tool which is most enerally employed for detachin caps of tis ty from the bottles is in t e form of two su stantially straightportionsfi and 7 connected at their ends by arms '8 to form a loop.In-removing the cap the portion 6 is'engaged beneath the elevatedportions of the retaining flange, and the portion 7 is engaged with thetop of the cap near or at its center in order to provide a wide bearingsurface, and to prevent the tilting of the tool, the top beingsubstantially flat and smooth or continuous in order that the tool maybe engaged therewith at any'point on its periphery.

While the smooth upper surface of the cap hasthe advantage mentioned, italso has the disadvanta e that the tool is liable to and often does s ipand in many instances cause a hand of an operator of the tool to engagethe retaining flange in a manner to injure the hand. To overcome thisslipping of the tool there is provided in this invention an tion extendsover and supports the greater portion of the sealing material that is.ex-'

posed to internal pressure within the bottle.

This arrangement not orfly permits the sealing material to be supportedefliciently by the flat portion when the projection is struck u and madehollow as shown, but the bar 7 oi the cap removing device may be causedto engage the cap substantially at the center. To secure a projection ofsuflicient height without destroying or breaking the 1 metal of the capduring the stamping or pressing operation it is desirable that thesmooth annular portion about the projection be very slightlyinclined'fromthe pe-' riphery of the capto the base of the projection asshown in Fig. 1. Internal pressure will force the sealing materialagainst the flat portion before the sealing material will be ruptured.

In removing the cap the tool is placed on the periphery so that thebar 6engages beneath the retaining flange and the ar 7 engages on theopposite side of-the projection 9 Upon upward pressure on the handle ofthey tool the bar 7 rldes downwardly on the projection to engage the top10 and to draw the bar "6 farther beneath the retaining flange, thusefiectively locking the tool to the cap. A further upward movement oithe tool removes the cap. I

A sealing device constructed in accordance with this invention costs nomore than devices now on the market and at the same time it positivelyprevents slipping of the removing tool, thus .insuring the operatorportion extending from the base of the proagainst injury and permittingthe cap to be removed more quickly.

I claim as my invention: 1. The combination with a bottle having a headprovided with an upper edge. of the bottle, of a cap covering thesealing disk and embodying a cone shaped projection with smooth externalwalls, a substantially flat'wide annular disk jection to'the peripheryof the cap and-supporting the greater portion of the sealing disk, and aretaining flange extending downwardly fromthe periphery of the. capintoengagementwith the exterior annular shoulider of the .bottle.

2. The combination with .a sealing element, of a cap for the sameprovided with a downwardly extending retaining flange, a centrallyarranged cone sha ed projection having smooth external walls, and asubexterior annular shoulder, and a sealing disk resting upon thestantially flat disk portion extending from the base of the projectionto the periphery.

3. The combination with a'sealing disk, of a cap for covering the samehaving a retaining flange extendin downwardly therefrom, ananti-slipping e ement arranged centrally of theitop of the cap andhaving a smooth inclined wall to be enga ed by a removing tool to drawthe latter. eneath the retaining flange, the top surface of the capbetween said element and the periphery be ing annular and substantiallyflat to provide a firm bearing surface for the tool.

4. The combination with a sealing disk,

of a cap covering the same and provided walls, a wide substantiallyextending from the base and a retaining flange extending ownwardly atthe periphery and provided with corrugations.
